将NSstring日期转换为UTC日期 [英] convert NSstring date to UTC date

问题描述

我需要将 NSString 中的某些日期转换为此格式的 NSString ： yyyy-MM-dd HH：mm：ss zzz
i写下这段代码：

i need to convert some date that i have in NSString to NSString in this format: yyyy-MM-dd HH:mm:ss zzz i write this code:

日期输入：日期---> 27/03/2012

-(NSString *)setDateStringFormat:(NSString *)date 
 {
     NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
     [formatter setDateFormat:@"dd/MM/yyyy"];
     [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
     //[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
     NSDate *dateFormatted = [formatter dateFromString:date];

     [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss zzz"];
     [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
 return [formatter stringFromDate:dateFormatted];
 }

输出：2012-03-27 00:00:00 GMT

因为你们都能看到我在 GMT 中得到的日期而不是 UTC
有人有想法吗？

as you all can see i got the date in GMT and not in UTC some one have an idea?

推荐答案

尝试这种方法..

-(NSString *)getUTCFormateDate:(NSString *)localDate
{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"dd/MM/yyyy"];

    NSDate *dateFormatted = [dateFormatter dateFromString:localDate];
    NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
    [dateFormatter setTimeZone:timeZone];
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    NSString *dateString = [dateFormatter stringFromDate:dateFormatted];
    [dateFormatter release];
    return dateString;
}
